Strasbourg could not play for the first leg due to a player testing positive to COVID-19. However, the primary reason for the suspension was a mistake made a few days earlier. Strasbourg did not undergo the mandatory PCR test two days before entering the hotel (the first testing had to be done 72 hours before the match, on Wednesday). As a result, it was decided that the match should be played on one leg, at Serbia, on the original date of the second leg.[4]
